Method for manufacturing catalyst for capture and conversion of carbon dioxide

A method of manufacturing a catalyst for capture and conversion of carbon dioxide, comprising:

• (a) preparing each of an oxide fine powder and a metal fine powder by pulverizing each a oxide powder and a metal powder, respectively;
• (b) preparing a crystallized synthetic zeolite by adding an alumina-based raw material, a silica-based raw material, and sodium hydroxide to a reactor with stirring;
• (c) preparing a first alkaline mixture by adding the oxide fine powder to the crystallized synthetic zeolite prepared from step (b) at predetermined time intervals with stirring followed by adding a first alkaline solution;
• (d) preparing a second alkaline mixture by adding a second alkaline solution to the first alkaline mix prepared from step (c) followed by adding the metal fine powder at predetermined time intervals with stirring;
• and
• (e) obtaining a catalyst for capture and conversion of carbon dioxide by preparing a third alkaline mixture by adding a third alkaline solution to the second alkaline mixture prepared from step (d) and stabilizing the second alkaline mixture for 40 to 50 hours, followed by extracting only a liquid portion,
